| Brake System | RED | Brake system fault or low brake fluid pressure compromises stopping ability on the JCB Telehandler 506-36. | Do not operate; check brake fluid reservoir and inspect for leaks. | |
| Parking Brake | AMBER | The parking brake is engaged; the machine will not move until released. | Release parking brake before attempting to drive or lift. | |
| Seat Belt | RED | Operator seat belt is not fastened; safety restraint system is disarmed on the JCB Telehandler 506-36. | Fasten seat belt immediately to enable machine operation. | |
| Glow Plug / Preheat | AMBER | Glow plugs are heating the combustion chamber for cold start assistance on the JCB Telehandler 506-36. | Wait until indicator turns off before attempting to start the engine. | |
| Low Fuel | AMBER | Fuel level is low; engine may stall if not refueled soon for the JCB Telehandler 506-36. | Refuel as soon as possible to avoid air in the fuel system. | |
| Hydraulic System | RED | Hydraulic system pressure or fluid level is low, limiting lift and steer functions on the JCB Telehandler 506-36. | Stop operation, check hydraulic fluid level and look for leaks. | |
| Fasten Seat Belt | RED | Seat belt reminder: belt is unbuckled while machine is in motion on the JCB Telehandler 506-36. | Fasten seat belt to silence alarm and ensure safety. | |
| Overload / Capacity | RED | Load exceeds the rated capacity of the JCB Telehandler 506-36, risking tip-over or structural failure. | Immediately reduce load or reposition to within safe limits. | |
| Mast / Lift Limit | AMBER | Mast height or reach is approaching the maximum safe envelope for the JCB Telehandler 506-36. | Operate cautiously; avoid over-extension or high lifts on slopes. | |
| Service / Hour Meter | GREEN | Display shows accumulated operating hours; indicates when scheduled maintenance is due. | Refer to maintenance schedule based on hour intervals. | |
| Work Lights | GREEN | Work lights are activated for improved visibility around the JCB Telehandler 506-36. | Turn off when not needed to conserve battery. | |
| Beacon / Rotating Light | GREEN | Rotating beacon is operating to alert nearby personnel of machine movement. | Ensure beacon is functional when operating in low-light or high-traffic areas. | |
| Differential Lock | AMBER | Differential lock is engaged for improved traction on soft ground for the JCB Telehandler 506-36. | Disengage on hard surfaces to prevent driveline damage. | |
| DPF / Regeneration | AMBER | Diesel particulate filter regeneration is in progress or required to clear soot buildup on the JCB Telehandler 506-36. | Allow regeneration to complete; avoid stopping engine during active regen. |

Most Important Warning Lights
Engine Overheating
Common causes
- Low coolant level
- Radiator blockage
- Faulty thermostat
What to do
Stop the engine and let it cool. Check coolant level and refill if low. Inspect radiator for debris. If persistent, have the cooling system checked by a JCB dealer.
Hydraulic System Failure
Common causes
- Low hydraulic fluid
- Leaking hose or seal
- Contaminated fluid
What to do
Immediately lower all loads and stop operation. Check hydraulic fluid level and top up if needed. Look for external leaks. Have the system inspected before resuming use.
Brake System Malfunction
Common causes
- Low brake fluid
- Worn brake pads
- Air in brake lines
What to do
Do not operate the machine. Check brake fluid reservoir and refill. If the light remains, have the brakes bled and inspected by a qualified technician.
Overload Condition
Common causes
- Exceeding rated load capacity
- Uneven load distribution
- Operating on an incline
What to do
Immediately reduce the load or reposition the machine to a stable, level area. Refer to the load chart for the JCB Telehandler 506-36 and never exceed the rated capacity.
Low Engine Oil Pressure
Common causes
- Low oil level
- Oil pump failure
- Clogged oil filter
What to do
Stop the engine immediately. Check oil level and add oil if low. If level is okay, do not restart; have the oil system diagnosed by a mechanic.
Frequently Asked Questions
What should I do if the Master Warning (Stop) light comes on?
Stop the engine immediately and safely. The JCB Telehandler 506-36 has detected a critical fault that could cause damage or injury. Check the display for additional information and contact JCB service.
How do I reset the service hour meter after maintenance?
The service hour meter reset typically requires a diagnostic tool or specific key sequence. Refer to the operator's manual for the JCB Telehandler 506-36 or ask your dealer to reset it during routine service.
Can I operate with the amber Master Caution light on?
Yes, but only temporarily. The Master Caution indicates a non-critical issue that should be addressed soon. Check other warning lights and schedule an inspection to prevent further problems.
What does the DPF regeneration light mean, and what should I do?
It means the diesel particulate filter is clearing soot. Allow the regeneration process to complete; do not turn off the engine during active regen. If it flashes, manual regen may be needed; follow the manual instructions for the JCB Telehandler 506-36.
Why is the overload light flashing even though my load is within limits?
It could be due to an uneven load, operating on a slope, or a faulty sensor. Ensure the load is centered and the machine is on level ground. If the light persists, have the load sensing system checked by a technician.
How often should I check the hydraulic fluid level on the JCB Telehandler 506-36?
Check the hydraulic fluid level daily before operation, especially if the hydraulic warning light has appeared. Top up with the recommended fluid only when the system is cool.
